There's probably someone here who can help with the issue you describe,
as there's occasional posts here and there from people who experience
issues/problems when using very large amounts of RAM.

I've got an amd64 machine with 48 GB of RAM that has run 7, 8, and now

the amount of memory.


Edge case at 64G perhaps? That's the minimum you can get in the HP
